One of the biggest myths in the hobby is that flow and turn-over rate is important. If I have two Sunsun 304s on a tank with two plastic pot scrubbers in each filter turning over the water 6X per hour, will this be better than one Sunsun 304 filled with forty plastic pot scrubbers and turning over the tank at 2X per hour? Of course not! It is the volume of the filter and the surface area of the filter media which is important, not the turn-over.<\/p>\n\n\n\n
The concept that flow is important was tested. It showed doubling the flow rate added some 9% to the filter capacity. All the social media gurus say it should double the capacity. This test can be found at this link:<\/p>\n\n\n\n
